Detailed Description

Frequency domain high pass.

This filter only works on an image after it has been converted to frequency domain by a vtkImageFFT filter. A vtkImageRFFT filter can be used to convert the output back into the spatial domain. vtkImageButterworthHighPass the frequency components around 0 are attenuated. Input and output are in doubles, with two components (complex numbers). out(i, j) = 1 / (1 + pow(CutOff/Freq(i,j), 2*Order));

Member Function Documentation

static vtkImageButterworthHighPass* vtkImageButterworthHighPass::New (   )  [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on. Reimplemented from vtkAlgorithm.

virtual const char* vtkImageButterworthHighPass::GetClassName (   )  [virtual]

Reimplemented from vtkThreadedImageAlgorithm.

static int vtkImageButterworthHighPass::IsTypeOf (  const char *  type  )  [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h. Reimplemented from vtkThreadedImageAlgorithm.

virtual int vtkImageButterworthHighPass::IsA (  const char *  type  )  [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h. Reimplemented from vtkThreadedImageAlgorithm.

static vtkImageButterworthHighPass* vtkImageButterworthHighPass::SafeDownCast (  vtkObject *  o  )  [static]

Reimplemented from vtkThreadedImageAlgorithm.

void vtkImageButterworthHighPass::PrintSelf (  ostream &  os, vtkIndent  indent )  [virtual]

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes. Reimplemented from vtkThreadedImageAlgorithm.

virtual void vtkImageButterworthHighPass::SetCutOff (  double  , double  , double  )  [virtual]

Set/Get the cutoff frequency for each axis. The values are specified in the order X, Y, Z, Time. Units: Cycles per world unit (as defined by the data spacing).

virtual void vtkImageButterworthHighPass::SetOrder (  int   )  [virtual]

The order determines sharpness of the cutoff curve.

virtual int vtkImageButterworthHighPass::GetOrder (   )  [virtual]

The order determines sharpness of the cutoff curve.

void vtkImageButterworthHighPass::ThreadedRequestData (  vtkInformation *  request, vtkInformationVector **  inputVector, vtkInformationVector *  outputVector, vtkImageData ***  inData, vtkImageData **  outData, int  outExt[6], int  id )  [protected, virtual]

If the subclass does not define an Execute method, then the task will be broken up, multiple threads will be spawned, and each thread will call this method. It is public so that the thread functions can call this method. Reimplemented from vtkThreadedImageAlgorithm.
